Due to the material’s elasticity, the X1 foot pocket offers greater size tolerance. Its snug fit provides excellent wrap-around comfort, enhancing power transmission efficiency. However, prolonged use may cause slight pressure. For users who prioritize comfort over maximum efficiency, it is recommended to choose a fit that ensures a more relaxed feel.
Fitting Reference Chart
Note 1: If your measurements are close to those of the model shown wearing the Thin Pads, we recommend choosing that size and adding the thin pads. If your foot length and width match the measurements but you have a lower-volume instep, you may use the thick pads instead to achieve a more secure and comfortable fit.
Note 2: If you have mild or severe bunions (hallux valgus), your forefoot width may be wider than your actual foot structure. Please refer to the measurements shown under "With Bunion" in the chart. We recommend considering both your foot width and the thickness of the socks you plan to wear, and sizing up when appropriate.
